VEHICLE-LEVEL'ER.

'Application filed J ui1e 18, 1917. Serial I T 0. 175,511.

T0 all wlwm z't may conoem:

Be .it known that I, MATHIAS HAUPT, a citizen of the United States, residing at Spokane, in the county of Spokane and State 0f Washington, have invented certain new and useful Improvements in Vehicle-Levelers, of Which the following is a specification.

My invention relates to improvements in vehicle levelers.

One object thereof' is the provision of 0011- veniently arranged, kalfective, and novel adjusting mechanism operable from the drivers seat, whereby the frame of the v@hicle, Which is intended for the support of plovvs, seeders, harrows a11d other farm cultivators 0f like Character, may be maintained in a substantially level position when in use 011 hilly, sloping ground. v

An additional object is the provision of a construetion, mechanism, and arts of extrenne simplic1ty, Which may be manufactured Very cheaply, and Which will be very rigid, strong, and durable.

The invention resides in the novel combination, arrangement, am]. details of eonstruction Which will be hereinafter fully pointed out and described in connection with the accompanying drawings, in WhiCh- Figure 1 is a top plan vievv of a vehicle embodying my invention, the crank axles being in the poeitions they assume when adjusted to level the vehicle frame 011 sloping ground.

Fig. 2 is a rear elevation of the vehicle shown in Fig. 1 and illustrating' the adaptability of the leveler on sloping ground.

Fig3 is a fragmental, part sectional view in side elevatioxi, showing the arrangement 035 the worm-gear adjusting mechanism.

Referring more specifically to tne drawings, in which like characters of reference are used to indicate like parts in the several views, the numeral 1 designates a vehicle frame, preferably 0f metal construction, and having a transverse cross-bar 2. A pair of crank-axles 3 and 4 have integral shaft portions 8 and 4:, respectively, which extend in spaced parallel relation transversely 011 the frame, each axle being revolubly mounted in a bearing 5 secured to one of the frame sides, the axle extending through a bearing aperture in said side, and having its immer end revolubly mounted in a stub-bearing 6 upon the opposite side of the frame. The traction wheels 0:f the vehi cle are mounted upo11 the outwardly extended ends of said crank-axles. The .axles are provided with and geared together by fixedly mounted, intermeshing, toothed gears 7 and 8.

A bracket 9 and a bearing 10, both secured t0 the cross-bar 2, rotatably support a slant- 1ng operating shaft 11 having a band wheel 12 and a worm-gear 13 Which Worm gea1 meshes with and is adapted to rotate a toothed gear Wheel 14 fixedly mounted 011 the -forward crank axle 3. The hand wheel 12 1s disposed so as t0 be c0nvenient for operation from the drivers seat 15 Whieh latter is supported by a curved spring 16 extending upwardly from the Vehicle frame.

In actual use 01 the leveling mechanism, it is obvious that turning 0f the hand wheel in one direction 01 rotation Will serve to elevate one of' the vehicle Wheels relative to the frame and at the same time t0 correspondingly depress the opposite vehicle Wheel. The effect is, of course, reversed by turning the hand wheel in the opposite direetion. It is to be especially noted that by reason 0f the simultaneous raising and 10W ering 0f the opposed vehicle wheels the desired leveling of the frame when sloping ground is encountered may be very quickly etfected. This feature is therefore a de cidedly more advantageous arrangement than separately operated crank axles. The WOIIll gear action is positive, convenient t0 operate, and eliminates the necessity for a device to lock the axles in adjusted position, such as would be required were a lever action employed to elfect the turning 0f the axles. Applicant is aware that crank axles have been used for the same purpose as the present deviee and he therefore disclaims as his invention the broad principle of operation involved; but he does 11011 believe that anyone has heretofore provided a leveler embodying the several features of construction herein set forth.

- Having described my improvements, I claim:-

l. Ina vehicle leveler, a vehicle frame, a pair 0f crank axles each revolubly mounted and supported in bearings carried by the opposite sides of said frame, integral shalt portions of the axle disposed in spaced, parallel relati0n, toothed intermeshlng gears fixedly mounted on said integral shaft portions of the axles, an additional toothed gear additinal gear.

' 2. In a vehicle level(ar," a vehicle fraiiie, a

pair of crank axles each reyolublymounted and supported in bearings 'carried by tl1e opposite sides of said fran1e, integral shafu -port1ons 0f the axles d1sposed 111 spaced,

parallel relation, toothed,intermeshing gears fixedly m ounted on said integral shafp portions 0f tl1e axles, an additional toothed geu1 fixedly mounted 011 one of said shaft purtions, a transverse cross-bar extending etween the sides of' the vehicle f1ame, a bracketand a bearing secured thereto, a shaft revolubly supported by said biack0t aiid bearing, and a wenn gear 011 said shaft meshing with said additional gear.

In testiinony whereof I aflix my signaturo.
